Fiber optic cables have a core that carries light to transmit data. This allows fiber optic cables to carry signals at speeds that are only about 31 percent slower than the speed of light—faster than Cat5 or Cat6 copper cables. Therefore, it also brings less signal degradation with fiber cables.
Fiber optic cables provide more bandwidth for carrying and transmitting more data than copper cables of the same diameter. Within the fiber cable family, single-mode fiber delivers up to twice the throughput of multimode fiber. Like a highway which has a larger space for cars to pass through, meaning faster speeds.
Although some fiber optic cables may have a higher initial cost than copper, the durability and reliability of fiber can make the total cost of ownership (TCO) lower. And costs continue to decrease for fiber optic cables and related components as technology advances.
With Its disadvantages, it also brings similar similarities which it also divides both copper and glass as follows:
Fiber optic cables are often more fragile than normal network cables. For example, the fibers can be broken by bites from rats or a signal can be lost if the cable are bent or curved around a radius of a few centimeters.
SYSTEM PLANNING & DESIGN
Excessive loss of signals can occur due to single-modes or multi-modes fibers. This is because of the cable is fragile, which requires a skillful technician to overcome the challenge of the environment, its length and the cores of fiber transmission.
The fiber optic glass is vulnerable to contamination which can cause extensive signal loss can also occur due to a contaminated connector. Things like dust, fingerprints, scratches and humidity of the air can contaminate connectors.
